Sayyiduna Shaddad bin Aws (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings be upon him) said: "That you leave your heirs wealthy is better than that you leave them dependent, stretching out their hands to people. And you will not spend anything seeking the pleasure of Allah except that you will be rewarded for it, even the morsel you put into your wife's mouth."
